okay so i have a HD7970.(Driver version 12.104) ....i run bf3 all maxed out + FXAA INJECTOR.......i have recently noticed that with Vsync on my GPU usage varys around 60-80 (mostly stable fps 54-60) and with V-sync OFF it goes all the way up to 99-98% (fps 54-79) i wanted to know if the gpu usage i am getting with V-SYNC on is okay or should it always be at 100% even with v sync on........!
